Abstract: ABSTRACT OF DISCLOSURE:       A hood assembly for use with cooking equipment having a plurality of units for separating foreign matter from air moving through the hood assembly.  Each unit has a cylindrical tubular member having a passage for carrying the air and entrained foreign matter.  A plurality of helical elements are located in the passage.  The adjacent helical elements are located in 90° relationship relative to each other so that the air moving through the passage is divided into sep-arate helical paths which direct the air in spiral patterns whereby the foreign matter is separated from the air by the mechanisms of centrifugal force, adhesion and impaction.  The foreign matter is collected and carried to a container.  The cleaned air is recycled into the environment surrounding the hood assembly.

Abstract: SELF-ALIGNED INTEGRATED CIRCUITS                  ABSTRACT OF THE DISCLOSURE:                  Semiconductor integrated circuits, including, e. g., field effect transistors and memory cells employing field effect transistors, are formed by providing at a surface of a semiconductor substrate a pair of isolation mediums and a plurality of spaced apart conductive lines extending between the isolation mediums.  The conductive lines, such as polycrystalline silicon or polysilicon lines, are preferably thermally, chemically or anodically self insulatable in an unmasked batch process step and are made of a material suitable for defining a barrier to a dopant for the semi-conductor substrate.  Signal or bias voltages are applied to selected or predetermined conductive lines to provide control electrodes or field shields for the transistors.   When the substrate has deposited on its surface an insulating medium made of a dual dielectric, such as silicon dioxide-silicon nitride, the dopant may be ion implanted through the insulating medium to form, e. g., the source and drain electrode of the transistors as defined by the isolation mediums and the conductive lines.  Other elements may be added to the structure to form, e. g,, a memory cell.  By depositing a conductive medium over the insulated conductive lines, the medium may be appropriately etched to provide desired access lines, capacitor electrodes, ground planes or additional field shields for the cells.

Abstract: ABSTRACT OF THE DISCLOSURE          A sheet of camouflage material is provided for concealing people and equipment from people or animals having a sense of color or geometric perception.  The sheet has a plurality of alternating rows of straight-sided, upright V-shaped cuts with intermediate rows of inverted V-shaped cuts.  The upright V-shaped cuts line up vertically in alternating columns with intermediate columns of inverted "V" cuts.  Each shaped cut is comprised of a long straight incision and a short straight incision which intersect to form a triangularly-shaped point.  The ratio of the lengths of the short incision to the long incision and the ratio of the spacing between points of the adjoining shaped cuts in a column and the length of the long incision are defined so as to produce a sheet of camouflage material which, when stretched, produces a three-dimensional effect with sharp points simulating grass or leaves with a height in the third dimension between three and four times the height of previous incised camouflage sheets.  The increased height or increased third dimension improves concealment from radar.          Controlled stretching of the sheet results in a particular and predictable see-through factor which is commensurate with the radar return.  Less blades are necessary to incise the material and they are cheaper to build and cheaper to maintain.

Abstract: ABSTRACT OF THE DISCLOSURE     It is known to construct amusement devices which include a transparent container filled with a body of transparent fluid, at least  one object located within the body of the fluid and a pump or pump type structure for circulating the object within the fluid so as to move the ob-ject relative to a structure such as a holder or a simulated basket within the container.  Such amusement devices can be improved by utilizing a target type holder at least part of which is movably mounted within the interior of the container.          The pump employed includes a port located so as to be capable of directing a current of the fluid generally toward the movable part of the target so that the pressure of the current against this part of the target will cause it to move as the pump is operated to eject fluid through the port.  The movable part of the target is located within the container so that its position as determined by the operation of the pump affects the relative difficulty of moving an object so that it is retained by the target.

Abstract: ABSTRACT    A method for controlling the decelerated approach of an aerodyne on radio-alignment generally referred to as "glide", in particular for the purpose of reducing its fuel consumption and reducing the noise, mainly in the final stage of the approach, by approaching the glide at high speed, initiating the descent according to the glide angle, also at high speed, then beginning a decelerated phase in order to reach a predetermined speed V sel + k, k being generally equal to 10 knots, on reaching a predetermined altitude hF, and then passing progressively from the speed V sel + k to the speed V sel.  From the time when the aerodyne reaches the axis of the glide path, a course is determined in two sections, as regards the variables of speed and altitude, for reaching the point situated at the altitude hF at the given speed V sel + k, namely a first section, at the beginning of which the aerodyne which was previously travelling along the glide, begins a first braking stage, the speed of the aerodyne, during this first section, being reduced by at least a predetermined speed .DELTA. V1, and a second section, at the beginning of which the aerodyne initiates a second braking stage, the gradient ?   along these two sections having to satisfy the relationship P2  =  k P1 P1 and P2 being the respective gradients on each of the two sections and k being a value determined experimentally.

Abstract: JC:srd   20811-16  10/27/77 MULTIPLE BEAM OPTICAL RECORD PLAYBACK APPARATUS   FOR SIMULTANEOUS SCAN OF PLURAL DATA TRACKS     Abstract of the Disclosure An optical data record playback apparatus is described for simultaneously scanning a plurality of data tracks on the optical record by employing two or more light beams controlled by closed loop servos.          First and second optical servo means respectively, are employed to deflect the light beams for tracking of such beams during scanning along the data tracks and for main-taining the proper spacing between beams to cause each beam to follow a different track.  In addition, a time adjust means, which may be a third optical servo or an electronic signal delay means, is employed to adjust the time relationship of the two readout signals produced by such light beams.  The optical servos may include either movable mirrors or light refraction plates. Alternatively, an electromagnetically deflected bundle of optical fibers can be employed as the first servo and a zoom lens at the output of such fibers as the second servo.  Also, a double refraction polarizing device, such as a calcite crystal, can be employed as both the second and third servos by pivoting such crystal about two mutually perpendicular axes.

Abstract: ABSTRACT OF THE DISCLOSURE           Ammonium jarosite is converted to magnetite and ammonium sulphate.  The invention can be used for removing iron from a feed solution containing dissolved ferrous sul-phate.  The feed solution is treated with ammonium sulphate and oxygen to precipitate ammonium jarosite which is then separated from the treated solution to produce an ammonium jarosite slurry and a separated solution containing sulphate ions.  The ammonium jarosite slurry is treated with ammonia in the presence of ferrous ions to convert the ammonium jaro-site to magnetite and ammonium sulphate solution.  The ammonium sulphate solution is separated from the magnetite, and a por-tion of the separated ammonium sulphate solution is recycled to the ammonium jarosite precipitation step, the remaining portion of the separated ammonium sulphate solution being recovered.
